General information about Bali
Bali is an Indonesian island in the Indian Ocean, located between Java and Lombok. The island is known worldwide for its beautiful nature, culture and excellent diving opportunities. While Bali is certainly not the only island in Indonesia with great dive sites (think places like Komodo, Raja Ampat and Lombok) Bali has the advantage of being easily accessible from many major cities in Asia and even Europe. This makes Bali the most popular choice for travelers who want to enjoy Indonesia’s underwater world without spending hours traveling to remote islands.
Bali offers a wide variety of dive sites for both beginners and experienced divers, and the development of its tourism infrastructure makes it an accessible destination for all. This is exactly why Bali, despite having other wonderful dive sites in Indonesia, is the most famous island for divers worldwide.
Why dive in Bali?
Bali is one of the best diving destinations in the world, and for good reason. The island offers an impressive variety of marine life, from colorful coral reefs to fascinating sea creatures you won’t find anywhere else.
The island is located in the Coral Triangle, an area known as the world’s biodiversity hub. Bali’s underwater world is home to thousands of species of marine life, from colorful reef fish, nudibranchs and dwarfseahorses to larger creatures such as manta rays, turtles and even the majestic mola mola (moonfish). Divers may encounter huge schools of fish as they move among the coral and underwater formations.
In addition, Bali is home to some iconic dive sites, such as the famous USAT Liberty wreck in Tulamben, which attracts divers not only for its historical value, but also for the marine life the wreck has attracted. You can find moray eels, barracudas and an abundance of macro life here. And then there are the drift dives at Nusa Penida, where you can encounter manta rays and even mola mola while diving. The water is clear and the diving conditions offer a pristine environment where, with a little luck, you can spot the rarest marine animals.
Best travel time for diving in Bali
Bali is a great year-round diving destination, but weather and conditions can vary depending on the season. If you want the best visibility and warmest water, it’s important to know when it’s best to go. In short, the best period is from April to November.
Visibility
Bali’ sdiving season depends largely on weather conditions and sea currents. The best time to dive is from April to November. During these months it is dry season in Bali, which allows for clearer water and good visibility underwater. Visibility can vary between 10 and 30 meters, depending on location and weather. Dive sites such as Tulamben and Amed usually have the best visibility during this period.
Water temperature
Water temperature is pleasant all year round, ranging between 26°C and 29°C. Water temperature is an important factor to keep in mind for your diving gear; although you can usually dive comfortably with a 3 mm wetsuit, it can feel colder in some areas (such as around Nusa Penida). Also important to keep in mind what type of diving you will be doing: for depth dives and long dives you may want a thicker wetsuit, And also if you like muck diving it is recommended to bring a 5mm. You obviously move a bit less during a muck dive.
In the rainy months (December to March), it is a bit more unpredictable. There is more chance of current and limited visibility due to rain and storms. But this does not mean that diving is impossible during this period, but it is best not to plan your trip to Bali during this period.
Current
Bali is known for its diving with strong currents, especially at places like Nusa Penida and Menjangan Island. Although currents can be challenging, it also provides opportunities to see large marine life, such as manta rays and mola mola. Divers who want to avoid the current can opt for locations such as Tulamben or Amed, where the water is usually calmer.
| Period | Diving conditions | Wetsuit Advice | Details |
|---|---|---|---|
| April – November | Best visibility (10-30 m), calm sea, warm water | 3 mm (shorty or full) | Dry season, top months for diving |
| July – October | Greatest chance of mola mola at Nusa Penida | 3-5 mm full | Cooler water (22-26°C) due to upwelling |
| December – March | Less visibility, chance of rain, more current | 3 mm full or shorty | Wet season, still diveable, especially north and east |
When do you see mantas or mola mola?
In Bali, manta rays and mola mola are two of the most sought-after underwater inhabitants for divers. The chance to see these impressive creatures depends on the season and the right conditions.
Manta rays can be seen year-round, but they occur in greater numbers during the dry months from April to November. The best places to spot them are at Manta Point on Nusa Penida, where you can often see large groups of manta rays circling in the clear water. This location has strong currents, so it is best for advanced divers who are comfortable with currents. Manta rays can be found at depths between 10 and 30 meters.
The mola mola, or moonfish, is one of the most iconic and sought-after fish species for divers. These impressive fish can grow up to 3 meters wide, and their appearance is a magical experience. The best chance to see a mola mola is from July to October, when water temperatures are cooler and the fish come to the surface for a cleanup of parasites. Crystal Bay on Nusa Penida is the most famous location to see mola mola. Diving at these spots usually goes to 40 meters deep, and the currents can be strong, so this is ideal for advanced divers who can handle currents well.

What diving equipment do you need in Bali?
Diving in Bali does not require extremely specialized equipment, but it is important to know what you need – and what you may want to bring yourself. Whether you want to explore wrecks, look for manta rays or focus your lens on the smallest sea creatures, the right gear will help you get the most out of your dives.
Basic equipment
- Wetsuit: In the dry season, a 3 mm shorty or full wetsuit is usually sufficient. During the mola mola season (July-October) the temperature drops to 22-26°C and a 5 mm full wetsuit is recommended.
- Mask & snorkel: Comfort and fit are personal. Having your own mask is a good investment. You can also now easily go into the water for snorkeling!
- Open fins & dive shoes: If you will be doing shore dives in Tulamben and Amed, for example, it is nice to bring open heel fins with shoes. Then you never walk barefoot.
- Dive Computer: Highly recommended for safety and control of your dive profile. If you make a lot of dives, it’s nice to have your own computer so you always have the right data and history.
- BCD & regulator: You can also rent well at Bali’s dive schools.
Underwater camera and accessories
For lovers of underwater photography, Bali is a true paradise. Especially the muck sites in Amed, Seraya and Secret Bay are full of macro life: from harlequin ghost snails to tiny seahorses. For that, the right camera gear is essential.
What many photographers bring:
- Compact camera with underwater housing: choose a suitable camera to suit your purpose
- (Macro) lens: for muck diving
- Focus light: helps focus on small, moving subjects
- Strobes or flashes: indispensable for color and sharpness, especially in dark corners
Many dive centers also offer camera storage, rinse stations and support for photographers.

Practical information for your diving trip to Bali
Before you pack your dive gear and take the plane to Bali, it’s helpful to have some practical things in order. How long will the trip take, what is the local currency and what can you expect in terms of food and facilities? Below you will find everything you need to know to be well prepared, along with some great ideas for things to do outside of diving.
- Travel time: most flights to Bali take about 16 to 20 hours, usually with a transfer in cities such as Singapore, Doha or Kuala Lumpur.
- Time zone: Bali falls in the UTC+8 time zone, which means it is 6 or 7 hours later than in the Netherlands (depending on our daylight saving time).
- Currency: you pay with the Indonesian rupiah (DR). Pinning is possible in many places, but you always have to pay an extra fee of a few percent. Even for small amounts, it is not always possible to pay by debit card. So it is wise to carry cash with you for local stores, restaurants, entrance fees for temples or tips.
- Food and drink: Balinese food is tasty, affordable and surprisingly varied. Vegetarians and vegans are also welcome everywhere: tempeh and tofu are widely used. Do not drink tap water; bottled water is available everywhere.
- Health: Ask at the GGD what vaccinations are recommended. In tourist areas, medical facilities are usually well regulated.
